使用JavaScript在元素框外呈现的内容该怎么办？
如果内容在元素框外渲染，请使用overflow属性添加滚动。这将简化访问者阅读整个内容的过程。
示例
您可以尝试运行以下代码，以了解如何使用JavaScript中的溢出属性-
<!DOCTYPE html>
<html>
<head>
<style>
#box {
width: 450px;
height: 150px;
background-color: orange;
border: 3px solid red;
margin-left: 20px;
}
</style>
</head>
<body>
<p>Click to use overflow property and set scroll.</p>
<button type="button" onclick="display()">Set Scroll</button>
<div id="box">
<p>This is a div. This is a div. This is a div. This is a div. This is a div.</p>
<p>This is a div. This is a div. This is a div. This is a div. This is a div.</p>
<p>This is a div. This is a div. This is a div. This is a div. This is a div.</p>
<p>This is a div. This is a div. This is a div. This is a div. This is a div.</p>
<p>This is a div. This is a div. This is a div. This is a div. This is a div.</p>
<p>This is a div. This is a div. This is a div. This is a div. This is a div.</p>
</div>
<br>

<script>
function display() {
document.getElementById("box").style.overflow = "scroll";
}
</script>
</body>
